Russel Brand, 37, was linked to the 50-year-old Ghost star last month, but he is adamant there is no romance between them, reported Sun online.
"Demi Moore, as far as anything more physical goes - she is just at yoga. I really like her, she is really lovely. I just see her at yoga. She is an older lady, she is incredibly beautiful but that's that," Russell Brand said.
The comedian said that he is a big fan of yoga, and even invited his classmates into his house in Los Angeles for a group session.
"It is full of amazing women. That is a fact. It has been brilliant. The yoga centre I had been going to sacked our instructor, so I have moved everyone into my house. I had 30 people doing it in my house," Russell Brand added.
